Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a component supply device that is installed in an automatic assembly line for printed circuit boards and supplies electronic components.

"Prior Art" Conventionally, as the above-mentioned component supply apparatus, there is one that supplies electronic components in a so-called taped state affixed to a carrier such as paper tape.

That is, in this method, as shown in FIGS. 6 and 7, a bone tape 2 is pasted on a paper tape I, the lead 4 of the electronic component 3 is sandwiched between them, and the feed hole 1a of the paper tape I is inserted. The electronic component 3 is conveyed to a predetermined location by traveling in the longitudinal direction while being sequentially engaged with a feed roller or the like (not shown).

Further, the electronic components 3 transferred by the paper tape 1 are usually separated from the paper tape 1 by cutting the leads 4, and further, the main body portion 5 is held by a chuck or the like (not shown) and then mounted on a printed circuit board. The installation is sent to the process. In the supply line, the iW 1 electronic components 3 are held in an upright position (or tilted at a certain angle) on a paper tape 1, thereby being accurately positioned with respect to a chuck, etc., and transported. It is required to do 4.

``The problem that the invention seeks to solve'' However,
Among the electronic components 3 attached to the paper tape L, for example, the leads 4 may be bent due to an external force applied during transportation, and in such a case, as shown in FIG.
The main body portion 5 of the electronic component 3 may tilt from the upright position to the left or right, causing a misalignment with respect to the chuck, etc., making it impossible to hold the component, or causing the chuck to accidentally hold the component. There is a problem with it being destroyed.

The present invention has been proposed in view of the circumstances described in -1-, and is a component supply device Iv capable of keeping the posture of electronic components attached to a paper tape constant regardless of the bending of the leads.
The purpose is to provide e-.

"Means for Solving the Problems" [In order to achieve the first objective, the present invention provides a method for holding electronic component leads between a conveyor such as a paper tape and an adhesive tape and moving them together with the conveyor belt. In the component supply device, first and second guide members are provided on the sides of the travel path of the conveyance body, each of which presses a main body portion of the electronic component in a direction intersecting a plane including the conveyance belt. It was designed to be provided.

"Function" One of the guide members presses the main body of the electronic component held on the carrier, bending the lead of the electronic component, and tilting the main body in one direction. In addition, the other guide member can press the main body portion of the electronic component in the opposite direction to the above case, thereby bending the lead in the opposite direction and correcting it to a predetermined posture.

"Embodiment" Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 5. In addition, in the drawings, parts common to the conventional example are given the same reference numerals to simplify the explanation.

First, the configuration of the entire apparatus will be explained with reference to FIGS. 1 to 3. Paper tape as a carrier! is wound around a feed wheel lO and runs in the direction of the arrow in Fig. 1, and the electronic parts 3 are mounted by sequentially inserting protrusions 11 protruding from the outer periphery into the feed holes 1a° in accordance with the pitch. It is designed to rotate while being engaged. Also, the feed wheel
O is an electronic component 3 held at a constant pitch by the paper tape 1 while repeatedly rotating and stopping by being intermittently driven by mechanical or electrical means.
- fixed, position between cutter 12 and movable cutter 13
Sequentially sent to l and stopped at this position for a certain period of time +1=
Let's do it 1.

Further, on one side of the travel path of the paper tape 1, as shown in FIGS. 2 and 5, a first tape is provided which contacts the main body portion 5 of the electronic component 3 and presses the electronic component 3 in one direction. A guide member 14 is provided, and a main body of the electronic component I is provided in the section between the first guide member 14 and the fixed and movable cutters 12 and 13, as shown in FIGS. A second guide portion +)r15 is provided which contacts the portion 5 and presses the electronic component 1 in the opposite direction to the guide member 14.

On the other hand, above the cutters 12 and 13, a chuck mechanism 16 as shown in FIG. 4 (the path shown in FIGS. 1 to 3) is provided. ) from the position shown in Figure 4(b) to the 4'' position shown in Fig. 4(b) to hold the lead 4 of the electronic component l, and then transport it to the printed circuit board assembly device (path shown) and attach it to a predetermined position. Also, reference numeral !7 is a pusher, and this pusher 17 is used to push the electronic component l held by the chuck mechanism 16, as shown in FIG.
It has a function of pressing the main body portion 5 of the electronic component 1 downward to prevent it from falling off, and also of pressing the lead 4 toward the printed circuit board when the electronic component 1 is attached to the printed circuit board F2 (path shown). There is.

Further, reference numerals 18, 19, and 20 indicate component sensors such as optical sensors, and these component sensors I8, 19, and
20 has a function of detecting that the electronic component 1 has moved to a predetermined position between the fixed cutter I2 and the movable cutter 13 and starting the drive mechanism of the dual-power vines 12 and 13. .

In the apparatus purchased as described above, electronic components are supplied according to the following steps.

(1) When the feed wheel IO rotates, the electronic component 3 moves in the direction of the arrow in FIG. The lead 4 of each electronic component 3 is bent by being pressed by the pressing surface 14b, and is uniformly tilted to the left in FIG.

(11) Each electronic component 3 is sequentially moved to the second guide member 15
The guide surface 15a and the pressing surface 15b press it in the opposite direction to the state shown in FIG. 2, and it assumes a uniformly vertical posture.

(iii) Furthermore, when the paper tape 1 moves, it is fed between the fixed cutter 12 and the movable cutter 13.

Note that the stop timing of the feed wheel 10 is as follows:
Electronic components 3, 3... are set at appropriate intervals depending on the mutual pitch.

Furthermore, by repeating the steps (1) to (iii), the electronic components 3, 3, . . . are fed into the predetermined positions one by one. In addition, the electronic component 3 is
・Every time the data is sent between 13 and 13, the following operations are performed.

That is, when the component sensors 18, 19, and 20 detect that one electronic component 3 is placed at the above position, the chuck mechanism 16 descends from the position shown in FIG. 4(a) to the position shown in FIG. 4(b). In this state, the movable cutter 13 protrudes horizontally to cut the lead 4 between it and the fixed cutter 12, and then the chuck mechanism 16 moves up to hold the electronic component 3 in a predetermined position. and then transported to the fourth
Returning to the position shown in the figure, the leads 4 of the next electronic component 3 are cut.

Note that it is desirable that the protrusion m of each guide member be as large as possible so that the guide member can perform a predetermined function regardless of the amount of bending of the lead.

Furthermore, the carrier is not limited to paper tape;
Moreover, it goes without saying that the traveling route and the arrangement of the cutters are not limited to the one embodiment described above.

``Effects of the Invention'' As is clear from the above description, the present invention provides a method for pressing the main body portions of electronic components on the sides of the travel path of the conveyor of a component supply device in a direction that intersects the conveyor. A first and a second guide member are provided, and the electronic component held on the conveyor belt is pushed in opposite directions by both guide members, so even if the lead of the electronic component is bent, The effect is that the posture of the electronic components held on the conveyor belt can be maintained constant and the positioning relative to the cutter and chuck mechanism can be performed accurately.
